How to fill in username and password using DotNetBrowser

Question

public MainWindow()
{
    InitializeComponent();

    BrowserView webView = new WPFBrowserView();
    mainLayout.Children.Add((UIElement)webView.GetComponent());
    ManualResetEvent waitEvent = new ManualResetEvent(false);
    webView.Browser.FinishLoadingFrameEvent += delegate (object sender, FinishLoadingEventArgs e)
    {
        if (e.IsMainFrame)
        {
            waitEvent.Set();
        }
    };
    webView.Browser.LoadURL("https://console.api.ai/api-client/#/login");
    waitEvent.WaitOne();
    DOMDocument document = webView.Browser.GetDocument();
    DOMElement username = document.GetElementById("username");
    username.SetAttribute("value", "kimyong95@gmail.com");
}

This is my program which navigate to "https://console.api.ai/api-client/#/login".

I trying to fill "kimyong95@gmail.com" into the Email textbox in the website using .SetAttribute but it doesn't work.

Anyone know how to solved this?

Thanks!

In the provided sample code you are trying to modify element property via the element attribute. Element attributes cannot be used to modify element properties: What is the difference between properties and attributes in HTML?

Here is a sample code that demonstrates how to use the Value property for setting the input field value:

DOMInputElement username = (DOMInputElement)document.GetElementById("username");
username.Value = "kimyong95@gmail.com";

The sample by the following link demonstrates how to work with various form fields: https://dotnetbrowser.support.teamdev.com/support/solutions/articles/9000110038-setting-input-field-value-working-with-form
